Also of concern is a developing system, dubbed 92L, which has the potential to impact Florida and other U.S. coastal waters.

According to a National Hurricane Center report at 5 p.m. Thursday, the weather disturbance near the Caribbean has developed into Tropical Storm Harvey.

Also of concern is a developing system, dubbed 92L, which has the potential to impact Florida and other U.S. coastal waters.

But first, Tropical Storm Harvey.

The Air Force Reserve Hurricane Hunter Aircraft dispatched to the storm system reported that Harvey is located 250 miles east of Barbados and 355 miles east of St. Lucia moving west at 18 miles per hour. Harvey is currently holding maximum sustained winds of 40 mph.

A Tropical Storm Warning is in effect for Martinique, St. Lucia, Barbados, St. Vincent and the Grenadines. A Tropical Storm Watch is effect for Dominica.

A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within 24-36 hours.

A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within 24-36 hours.

On its current forecast track, Harvey should move through the Windward Islands and into the eastern Caribbean Sea on Friday.

Harvey is expected to produce rainfall totals of 2 to 4 inches across portions of the Windward Islands from Martinique southward to Grenada. These rains could cause life-threatening flash floods and mudslides.

Development possible for 92L

AccuWeather is projecting that 92L will pass over or just north of the Leeward Islands this weekend, and has the potential to develop into a much stronger storm.

"If 92L can overcome the dry air, it has a chance at becoming a depression or tropical storm this weekend," said AccuWeather hurricane expert Dan Kottlowski.

If 92L tracks north of the northern Caribbean islands, including the mountainous islands of Puerto Rico, Hispaniola and Cuba, AccuWeather is saying that would favor development and strengthening.

92L is currently being reported as having the greatest potential of the three systems in the Atlantic region for approaching the U.S. or its coastal waters next week.
